lhis invention relates to improvements in books formanifolding purposes.

In practice, it has been frequently possible to effect economies in paper and printing costs by having some of the tickets or forms making-up a set of manifolding Worksheets only as long as is necessary and omittingspace and delineations for such entries as are not really needed on such copies. This has been especially true since the appearance on the market of machines manufactured in accordance with the Shoup and Oliver Patent No. 1,396,070, by means of which it is possible to feed simultaneously forms of difi'erent lengths and yet have the setsof forms properly aligned and automatically so at the end of each feeding operation. Yet, it was heretofore supposed impossible to utilize these short and long tickets satisfactorily except in cases where the strips are not interfolded in zig-zag fashion to form a block or book.

This supposition was based on the fact that the forms of tickets are used in superposed sets, that is in duplicate, triplicate or quad-' ruplicate, etc, and since the extent of unfolding of the book in use would be controlled by the strips of the longer tickets, a surplus ofthe strip or strips containing the shorter tickets would accumulate and would tumble about in theregister or machine and would ultimately'become balled-up and torn.

While the basis of this supposition is not erroneous, the present invention obviates the difficulty above referred to by folding each strip, irrespective of the length of its tickets, in zig-zag fashion along the lines of perforations or other demarcationsbetween adjacent tickets, and then assembling or collatin the folded strips so that at one edge of the% the folds of the strip or strips having the longer tickets are nested with the corresponding folds of the strips having the shorter tickets, so that the forms to be used together lie in superposed relation in sets. Conse quently, 'the forms will be consumed in sets and will move from the pile or pack together irrespective of their lengths, and no ballingup of the strips in the register will occur.

7 Hence, it will be seen that this invention also embraces the method of making manifolding books which consists in separately folding the strip or strips of one length sheets separately from those of other length sheets folding book made in accordance with this invention.

Fig. 2 is a schematic view to show the rela tive positions of the strips of the finished book.

Figs. 3 and 4 are perspective views of the booklets of the longer and shorter tickets respectively, before they are collated or interspersed.

The book of manifolding worksheets shown in the accompanying drawings comprises a plurality of strips 10, 11, 12 and 13 of indefinite lengths. Each of the strips is formed of a succession" of tickets 14 which may be provided with printed matter 15, or which may be plain, as desired. Each ticket 14 is separated from its next adjacent ticket in the same strip by a line of perforations 16 along which the strip may be torn to sever one ticket from the next adjacent ticket. The line of perforations 16 also facilitates the operation of folding the strips since it weakens the strips at just theright place for the fold. Each ticket l i may also be provided with a pair of apertures 17 through the medium of which the feeding operation of the strip is controlled when the strips are used in a register such as disclosed in the Shoup and Oliver Patent No. 1,396,070, which is well known in the art.

It is frequently desired, for the purposes of saving in the cost of the book and for other purposes, to have certain of the tickets shorter in length than others, for it is not always necessary to have all of the information contained on certain of the strips duplicatedon other strips. For instance, in the form shown it is not necessary ,to have the delineated spaces 18, which are provided on the strips 10 and 11, also appear on the strips 12 and 13,

and hence the tickets 14 of the strips 12 and 13 may be shorter in length than the tickets of the strips 10 and 11.

While this is a desideratum which has been realized in connection with rolled stationaryv where each strip is rolled on a separate core,

it has been heretofore unobtainable in a zigzag folded pack or book of worksheets to have the strips folded in superposed relation ready for use, for if the strips 10, 11, 12 and 13 should be folded together in zig-zag fashion at predetermined distances governed by the form lengths of the longertickets 14 of the strips 10 and 11, it would be necessary for the longer tickets to pull themselves from between a stack of shorter tickets, as the consumption of the pack continues, with the result that the stack of shorter tickets would tumble about in the register and become balled-up and ultimately torn. j

The desideratum above referred to has, however, been obtained by the present invention by folding the strips having the same form lengths, which are the strips 10 and 11 in the form shown, separately and independently of the operation of folding the strip or strips having the shorter form lengths, '12 and 13 in the form shown. Accordingly,

the strips 10 and 11, the tickets of which are of the same lengths, are placed in superposed and registering relation and then are folded along the lines of perforations 14 in the usual manner, that is to say by hand, sothat a booklet 19 is produced. Then the strips 12 and 13,-which are made up of the shorter tickets, are likewise superposed and folded to produce the booklet 20; Finally, to pro duce the pack, it is merely necessary to inter- .With the worksheets so folded at each feed-' ing operation of the machine, one layer of forms or ticket will be taken from the pile and no surplus length of any strip is allowed to remain in the machine and become balledup with the other strips.

.The manifolding book of this invention may also be produced by the folding machine disclosed in my'copending application Serial No. 512,761, filed February 2, 1931, in which.

the folding machines disclosed in my Patent, No. 1,805,161, granted April 12, 1931, and in my application Serial No.392,540, filed September 14, 1929, have been improved and modified to provide a feed mechanism for feeding the strips form-lengths regardless of the lengths of the forms, so that in the folding operation the folds of the several strips extending in one direction will be nested while the folds in the other direction will be located where they happen to fall.

1 A manifolding book comprising afplurality of continuous superposed zig-zag olded worksheet strips, each strip havin a succession of forms separatedby lines of perforations along which the strip is folded, the forms of one strip being shorter than the forms of another, and having its folds in one direction nested with the folds of the other strip which are in like direction.

2. A manifolding book comprising a plurality of continuous superposed zig-zag folded worksheet strips, each strip having a succession of sheets with folds in opposite directions along the lines where the sheets adjoin, thedistance between the folds of one strip being greater than the distance between the folds on another of the stri s, and the folds in one direction of one o the strips being nested with the folds in like direction of another of the strips.

3. A manifolding book comprising a plurality of continuous superposed worksheet strips interfolded and nested within each other in zig-zag fashion, each stri having a succession of sheets the sheets of one strip being shorter than the sheets of another strip,'a-nd the strips being each folded along a line of perforations between successive sheets irrespective of the differences in sheet lengths.

A manifolding book comprising aplurality of continuous superposed zig-zag fold ed worksheet strips, each strip having a, succession of sheets, the sheets of one strip be ing shorter than the sheets of another strip, the strips being each folded along a line of perforations between successive sheets irrespective of the differences in sheet lengths, and the strips being nested with the folds in one direction in one of the strips engaging the folds in thesame direction of the others of the strips.

5. The herein described steps in the method of making a manifolding book having a plurality of zig-zag folded superposed strips, each of which is a succession of attached sheets and in which the sheets of one strip aregreater in length than the sheets of another strip. with the folds occurring at the junction of one sheet with another, which consists in zig-zag folding one of the strips to form a booklet, then separatively zig-zag folding the other of the strips to form another-booklet, and finally collating the sheets of one booklet with those of another to nest one booklet with the other. i v
